well....
those analog thermometers dont work, they are always off by so much
go to walmart, buy an acurite indoor/outdoor therm. it has two temps and humidity, its great (costs 15$)
and, i think that if you are using a heat pad and a heat light, they should be directly over/under each other, if there is too much of hotness in the cage, and the bp wants to be on the cooler side, it might not be able to escape the heat.
does this mean you only have one hide? you need a hide on both sides, so when he wants to be on the warm side, he can be secure, and vice versaand the cardboard hide is on the right side
